Why do we have to use renewable energies?

We have to use renewable energies because they are inexhaustible, and they are cleaner, natural and economical. They don't cause pollution and the sources are more abundant. 

Difference between renewable and non-renewable energies

Renewables energies are those energies that are produced continuously and they're inexhaustible, for example: solar energy, wind energy, water energy, biomass energy and geothermal energy.
Non-renewable energies are those from the nature and they take milions of years to form, for example: fossil fuel, coal and petrol.
